Application July 6, 1931. Serial No. 548,902 7 Claims." (01. 277-31) Myinvention relates to new and useful improvements in a gauge cook orvalve, and has for one of its objects to generally improve theconstruction of devices of this kind wherein the valve stop or plug maybe readily and quickly removed for grinding said valve stop and plug andits seat without having to shut oii any valves or without draining thewater from the article to which the gauge cook or valve is connected.

Another object of the invention is to provide a gauge cock or valvestructure which makes it easy to grind the valve stop or plug and itsseat.

Another object of the invention is to provide for shutting oil thecommunication between the inlet and outlet of the gauge cook or valveupon giviir an extraordinary openingmovement to the valve stop or plug.

Another object of the invention is to provide for reopening thecommunication between the inlet and outlet of the gauge cock or valveafter the parts have been replaced and the valve stop or plug been movedtoward its closing position but prior to the said valve stop or plugreaching its closed position.

Another object of the invention is to provide a device of this kindwhich requires little or no packing, the same being made non-leakable byground joints.

A further object of the invention is to provid unique means fortransmitting motion from the stopper to the disc closure or cut-off.

A further object of the invention is to provide a gauge cock or valveincluding a body having a housing connected thereto for enclosing a discclosure or cut-off which will control the passageway through the body orcontrol the communication between the inlets and outlets of the device,said disc closure or cut-off being actuated through the medium of gearson a shaft journalled in the housing with one of the gears meshing withteeth on the cut-off and the other meshing with teeth on a collarmounted upon-the valve stopper and controlled thereby under someconditions and also controlled directly by the operating handle undercertain other conditions and said collar being limited in the amountandkind of movements it can make.

With these and other ends in View, this invention consists in thedetails of construction and combination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by numerals to formed a circularthe accompanying drawings forming a part of this application, in whichFig. 1 is a side elevation of a gauge cook or valve embodying myinvention.

In carrying out my invention as herein embodied, 20 represents the bodyof the gauge cock or valve including a head 21 having arecess 22 in itsinner face and a shank 23 externally threaded whereby the device may bemountedon an article where it is to be used, for example,

a water gauge.

The formation of the recess 22 produces a flange 24 which is internallythreaded for the reception of the externally threaded plate 25,

the latter having a flange 26 at its outer end for a purpose to bepresently described.

A. bore 27 extends through the body while-a similar bore28 formedthrough the center of the 25 and aligns with the bore. 27 and in theinner face or recessfchambe'r or cavity 29 which is eccentric to theplate, as a whole, so that said chamber projects across, intersects orcommunicates with. the bore 28 and with the plate in place the saidrecess, chamber or cavity comend of the said plate 25 is municates withthe bore 27. While the bore 28 is concentric relative to the plate,being in its center, said bore is eccentric to the recess, chamber orcavity 29.

Within the recess, chamber or cavity 29 is revolvably mounted a discclosure or cut-off 30 having an eccentric hole 31 therethrough which canbe moved into and out of alignment with the bores 27 and and when insuch alignment the passageway including said bores 27 and 28 and thehole 31 is free for the passage of fluid but when the cut-on is rotateda short distance the hole 31 will be moved out of alignment with saidbores 27 and 28 and a solid portion of the cutofi will be disposedacross the passageway including the two bores thus closing saidpassageway to the passage of fluid therethrough. The cut-01f may berotated in various ways but one method will be hereinafter described.

A union nut 52 is connected with the plate 25 and. engages the flange 25on said plate for anchoring purposes and said union nut has threadedengagement with the hood 33 to removably connect the same with the bodyof the device. The hood is fashioned so that its inner end, or at thelower end as illustrated in Fig. 2, is provided with an exhaust chamber34 which is in communication with the passageway formed by .the bores 27and 28 and the hole 31 and with an outlet 35 through one of the walls ofthe hood. Just beyond the exhaust chamber 34, or outward therethrough,the interior of the hood is reduced in size and then enlarged to producea groove 36 with a rib 3'7 between said groove and the exhaust chamberand across this rib is formed a lateral key way 38 and across the groove35 to one side of the key way 33 is a stop 39, one face of which alignswith or forms a continuation of one of the sides of the key way,

To'the rear of the groove 36 the interior of the hood is further reducedin, size to provide a socket receiving chamber 40 while at the extremeouter end is formed a stufiing box 41 which is in communication with thesocket receiving chamber 40 through an opening '42 designed to receive apart of an operating handle 43.

The operating handle may be of any desirable configuration but shouldinclude a stem 44 on the outer end of which is mounted any suitablemeans, such as a wheel 45 for rotating the operating handle while at theinner end of said handle is an internally threaded socket element 45which is positioned in the socket receiving chamber 40 and where the endof said socket element 46, which joins with the handle engages thecontiguous wall of the socket receiving chamber a ground joint 47 isformed.

The socket 46 has threaded connection with the valve stopper or plug48which may be of any suitable or desirable construction but forconvenience of illustration only it is here shown similar to a needlevalve or a straight round rod like element having a tapered seating endwhich coacts with the valve seat 49 formed in the outer face or theplate 25 and surrounding the bore 28. While said seat 49 is at the outerend or face of the plate 25 said seat is at the inner end of thepassageway formed by the bores 2'7 and 28.

The stopper 48 is provided with a spline 50 which, for convenience ofillustration, is shown as a pin passing laterally through the stopperwith the ends or" the pin projecting beyond the surface of the stopperand registering with spline grooves 51 formed in a collar 52 which has abore therethrough whereby the collar may be slidably mounted on thevalve stopper. The collar 52 has a key 53 formed on its circumference atits rear or upper end so that under some conditions it may travel in thekey way 38 and in other conditions it will travel in the groove 36, andwhen travelling in said groove in one direction will be stopped andcaused to align with the key way 38 by the stop 39.

The threaded connection between the operating handle, or moreparticularly the socket 46 thereof, and the valve stopper 48 is by meansof left hand threads so that when the operating handle is rotated in theusual or right hand direction for closing the valve, the valve stopper48 will moved inward toward its seat the said valve stopper being movedlongitudinally inwardly or threaded out of the socket due to being heldagainst rotation by the spline 5 cooperating with the spline grooves 51in the collar when the key 53 of said collar is in the key way 38 toprevent ro-- tation of said collar. The reverse operation of theoperating handle will cause the valve stopper to move outward or awayfrom its and into thesocket 46.

The inner end of the socket 46 of the operating handle has any desirablenumber, rably two, of ratchet teeth 54 projecting therefrom with thefiat faces forward relative to the direction of travel of theratchet'teeth or the rotation of th operating handle when the latter isbeing operated for removing or backing the valve stopper from its seator counter clock-wise and under the same conditions the beveled faces ofsaid ratchet teeth are toward the rear. hese ratchet teeth 54 are forcooperation with similar opposed ratchet teeth 55 on the outer orcontiguous face of the collar 52 so that when said collar is movedoutwardly whereby the ratchet teeth 55 will be in the, path of travel ofthe ratchet teeth 54 the collar will be moved in the direction ofrotation of the operating handle either away from or toward the key way38, it being understood that the key 53 is in registration with thegroove 33 when the collar is moved outward, and when the movement of thecollar is such that the key 53 is travelling toward the hey way 38 assoon as the key 53 strikes the stop 39 the births" rotation of theoperating handle will cause the ratchet teeth 55 to ride under theratchet teeth 54 and therefore the collar will be forced inwardly sothat the key 53 will enter the key way 38.

It is the rotation of-the collar 52 that causes the rotation of thecut-off 3G and may be accomplished by a gear and pinion memberconsisting of a gear 58 on one end of a shaft 5'7 and a pinion 58 on theopposite end of said shaft, said pinion preferably being out on or intothe shaft so as to be no larger than the latter. Of course, the entiregear and pinion member as shown in Fig. 10, might be made from one pieceof material.

Said gear and pinion member is journallod, through the medium of itsshaft, in the plate 25 so that the pinion 58 is located within thecavity 22 while the gear 56 is located within the exhaust chamber 34.The gear 55 meshes with a gear 59, preferably of the segmental type, to.ned on or carried by the collar 52 and the teeth of said gear 59 are ofsufficient length to permit the necessary movement of the collar withoutdisengaging from the gear 56. or car element 60 formed on or carried bythe disc closure or cut-off 3t and said gear or gear element ispreferably of the segmental type and located within the confines of anarcuate slot 61 produced in the cut-off 30. From this it will be Thepinion 58 meshes with a gear l lei-O obvious that the rotation of thecollar 52 will rotate the cut-oil by the motion being transmittedthrough the gear of gear element 59, the gear 56, shaft 57, pinion 58,and the gear or gear element 60. j

While it may not be essential due to the provisions of the ground joint47, I prefer to pack the operating handle to positively prevent anyleakage and therefore I have shown a packing 62 in the stufing box iland held in place by a follower 63 which, in turn, is held in place bythe gland nut 64 having threaded connection with the outer end of thehood.

For a description of the operation it will be assumed that the gaugecock or valve is attached to a steam or water gauge of a boiler. To makea test, the operating handle 43 is rotated counter clock-wise and sincethe valve stopper cannot rotate therewith said valve stopper will bemoved outwardly by threading into the socket 46 whereby the valvestopper will be unseated and the fluid may now from the object on whichthe valve is mounted through the bore 27, hole 31, bore 28, exhaustchamber 34 and the outlet 35. A reverse operation will again seat thevalve stopper.

When it becomes necessary or it is desirable to regrind the valvestopper and its seat, said valve stopper is first withdrawn from itsseat as above stated and when withdrawn a sufficient distance that thepressure will be built up in the exhaust chamber 34 due to the area ofthe outlet being smaller than the passageway formed by the bores 27 and28 and the hole 31, so as to move the collar 52 outwardly to disengagethe key 53 from the key way 38 or move said key into the groove 36. Thisoutward movement of the collar 52 will posi tion the ratchet teeth 55 onsaid collar in the path of travel of the ratchet teeth 54 on the socketof the operating handle and therefore the continued counter clock-wisemovement of the operating handle will cause the collar 52 to move withsaid operating handle in the same direction. The rotary movement of thecollar will cause motion to be transmitted therefrom through its gear orgear element 59 to the gear 55, shaft 57, and pinion 58 and thencethrough the gear or gear element 60 to the cut-off 30 so that the latterwill be rotated and cause the opening 31 to move away from the bores 27and 28 and dispose a solid portion of the cut-off 30 across or betweensaid bores thereby closing the passageway consisting of the bores 27 and28 and the opening or hole 31. This is especially true due to the groundjoints between the cut-on 30 and the body and plate 20 and 25,respectively.

The passageway through the body of the device being closed the union nut32 may be backed off and the hood with its component parts removed fromthe body of the valve thereby exposing the seating end of the valvestopper and its seat for the application of abrasive material and forcarrying out the grinding operaticns.

As soon as the valve stopper and its seat have been regroimd the hood isreplaced and the operating handle then rotated clock-wise in the mannerfor closing the valve. This operation will cause the beveled faces ofthe ratchet teeth 54 and 55 to come in contact with each other and thecollar 52 will be rotated until the key 53 thereof contacts with thestop 39. The key 53 then being in alignment with the key way 38,continued rotation of the operating handle will cause the ratchet teeth5% to push inward on the ratchet teeth 55 so that the latter will rideunder the former and move the entire collar inward with the key 53entering the key way 38. The reverse rotation of the collar willtransmit a reverse movement to the cut-off 35 and as soon as the key 53engages the stop 39 the hole 31 will be in alignment with the bores 27and 38 so as to again open the passageway through the body.

The collar being held against further rotation, the continued movementof the operating handle will screw the valve stopper inward toward itsseat finally bringing said valve stopper in actual engagement with thevalve seat to close the valve.
